Vaccume leak?
 

I recently got my bofi racing turbo kit installed (1.6l), and going through the steps of getting everything going right. I noticed that my vacuum is at around 16.5 Hg at idle. I live in Colorado, with a baro pressure of 82-83. My MAP pressure bounces from 27-29 at idle. It occasionally idles a bit rough, but that may just be from the warmup tuning. My idle is around 1100-1200 rpm currently.
